How to write int16 image data into Tiff or any other image format?

Hi, I have 512*512 int16 image data which I want to save as an image. However it can't be saved as a jpeg by imwrite. I tried Tiff instead using im2double,

con=im2double(image_data)
filename=['C:\Users\student\Desktop\brain\images\pituitary', '.tiff'];
imwrite(con,filename);

Result is a noisy picture due to the conversion

How to deal with int16 image data and obtain a clear reconstruction? .

Images must be uint8, uint16, single, or double format.
